Comparison of Indoor Radon Reduction Effects Based on Apartment ...
The concentration ratio (Cr) was estimated to present the indoor radon increase/decrease ratio. Among the natural ventilation scenarios, Case 3 had the highest radon reduction rate in the living room and Case 1 in the room, and Case 2 using natural ventilation equipment showed the lowest reduction rate in both the room and the living room.
Ventilation systems - Reduction of radon gas concentrations in a building can also be achieved through dilution of indoor air using balanced ventilation systems as provided by example systems such as a heat recovery ventilator (HRV) or an energy/enthalpy recovery ventilator (ERV).
Natural ventilation in any type of house should not be considered radon mitigation since it is only a temporary strategy to reduce radon . Seal cracks in floors and walls with plaster, caulk, or other materials designed for this purpose. Always test radon levels again after you've made any of these changes.
Useful Notes on Apartment Radon Mitigation Using Natural Ventilation
In general, increased ventilation methods for radon reduction will be most successful in houses that are more airtight and have low natural ventilation rates (are not 'drafty').
